Text on the box: "contact lenses".

I saw picture there Silver (from Pokemon Special) had golden eyes. And in new style (his hairdress) he has a... horn?.. And I have recollected Tao Ren (from Shaman King, yes).
And Ren's first (and TRUE! ХD) color of eyes is violet! And Silver is... silver. o.o Are golden-eyed boys more popular?
